Making an Emergency Call
The satellites used by the GPS feature of your
phone are controlled by the U.S. government and
are subject to changes implemented in accordance
with the Department of Defense GPS user policy
and the Federal Radionavigation Plan. These
changes may affect the performance of the GPS
feature of your phone.
Making an Emergency Call
Dial 911 to be connected to an emergency
response center. If you are on an active call, you
must end it before calling 911.
When you make an emergency 911 call, the GPS
feature of your phone begins to seek information to
calculate your approximate location. It will take
the GPS feature of your phone some time to
determine your approximate location. Even
where your phone has good access to sufficient
GPS satellite signals and network assist data, it
may take 30 seconds or more to determine the
approximate location. This time will increase where
there is reduced access to satellite signals. When
your approximate location is determined, it is made
available to the appropriate emergency response
center.
In some cases, your local 911 emergency
response center may not be equipped to
receive GPS location information. For this
reason, and because the GPS location information
reported is only approximate or may not be
available in your location (see “IMPORTANT:
Things to Keep in Mind” on page 127), always
report your location to the 911 operator you
speak to when making an emergency call, if able,
just as you would when using a phone without GPS
capabilities.
Note: If you are concerned about whether your
local 911 emergency response center is
equipped to receive GPS location
information, contact your local authorities.
In general, if your phone has access to signals
from more GPS satellites, your location will be
determined faster and more accurately than if your
phone has access to signals from fewer GPS
satellites.
If your phone does not have adequate access to
GPS satellites signals, the location of the nearest
cell tower in contact with your phone is
automatically made available to the emergency
response center, if the center has the capability to
receive such information.
